## 🔒 Security

### 🛡️ Security Best Practices

- **API Key Protection** - Never commit `.env` files or API keys to version control
- **Per-Network Wallets** - Each network has isolated wallet configuration
- **Private Key Security** - Private keys never leave your environment, only used for signing
- **Environment Variables** - All sensitive data stored in environment variables
- **Input Validation** - All inputs validated before processing
- **EIP-712 Signatures** - Secure withdrawal signatures following Ethereum standards
- **Rate Limiting** - Built-in rate limiting prevents API abuse
- **Secure Communication** - HTTPS for all external API calls
- **Error Handling** - Errors don't expose sensitive information

### 🔐 Wallet Configuration Priority

The server uses this priority order for wallet credentials:
1. **User-provided private key** (in tool parameters)
2. **Network-specific private key** (from `NETWORK_WALLET_PRIVATE_KEY` env var)
3. **Network-specific mnemonic** (from `NETWORK_WALLET_MNEMONIC` env var)

### ⚠️ Important Security Notes

- **Solana private keys** must be in base58 format (NO 0x prefix!)
- **EVM private keys** must be in hex format WITH 0x prefix
- Keep separate wallets for different networks if needed
- Use hardware wallets or secure key management in production
- Never share your private keys or mnemonics
